Cornell law professor Sherry F. Colb and George R. El-Khoury, JD, comment on a decision by the U.S. Supreme Court last month applying the “exigent circumstances” exception to the warrant requirement to permit the admission in evidence of a blood-alcohol test administered on an unconscious driver. Colb and El-Khoury describe some of the problems with using the exigent circumstances exception to arrive at the result in this case and propose some alternative approaches that might yield the same outcome but for stronger reasons.
